WHEEL-CULTlVATOR.

SPECIFICATION forming part of Letters Patent No. 385,108. dated `u'ly 1'7, 1888.

Application filed April 2, 188B. Serial No. 269,804. (No model.)

To all whom, it may concern:

Be it known that I, Ross COHOON, a citizen of the United States, residing at Crawfordsville, in the county of Montgomery and State of Indiana, have invented a new and useful Improvement in NVheel-Cultivators, of which the following is a specification.

My invention relates to an improvement in that class of wheel-cultivators commonly known as tongueless, and which consists of two gangs of cult-ivator-plows, each having a carrying-wheel and both connected to a common draft-bar.

The object of my improvement is to provide means whereby either or both of the carryingwheels may be independently turned to forni an angle with the line of draft by the person holding the plow-handles swinging the handles upon the plow-beams, and thus turning the wheels so as to draw the plow-gangs around an obstruction or a plant, and thus avoiding the frequent lifting ofthe plows, all as hereinafter fully described.

The .accompanying drawings invention.

Figure l represents aside elevation looking from the center between the plow-gangs outward. Fig. 2 is a front elevation ot' the same. Fig. 3 is a plan. Fig. 4 is a central vertical section on an enlarged scale, showing the manner of coupling the carrying-wheel spindles to the axle. Fig. 5 is a transverse section ofthe same at c, Fig. 4.

A is the plow-beam carrying the plows I) b.

Bis a short aXle having an arm, G, which projects at a right angle from the axle, and is rigidly secured thereto,preferably by welding. Arm C enters a slot in the end of the plowbeam, and is rigidly secured therein by means of bolts d d, so that the axle B projects outward at a right angle with the plow-beam.

The outer end of axle B terminates in a forked arm, E, in which is pivoted, by means of boltsff, so as to swing in a horizontal plane, a short cylindrical wheelspindle, H. rIhe illustrate my inner end of spindle H is larger in diameter than the outer end, and is provided with an annular recess, 13, whose smaller diameter is the same as that of the outer end of the spindle, the purpose being to form a long bearing for the hub j of the carrying-wheel k, which shall project about equally on each side ofthe wheel. The back side of hubj is recessed, as at Z, to receive the outer end of the forked arm E, the purpose being to bring the pivotsff in line with the center of the rim of the wheel.

N is an arm,which is rigidly secured to spindle H and projects backward therefrom.

O is a bent lever, which is pivoted to the plow-beam at p, and is connected to arm N by a bolt, q, which slides in a slot, r, in the arm.

The plow-handle S is rigidly secured to le- Ver O, so as to form an extension thereof, and has on one side an eye, t, through which pivot p projects.

'I is an arched draft-bar, to which the plowbeam A and axle B are connect-ed by a coupling-beam, a. Coupling-beam u is hinged at its forward end to the draft-bar to allow the latter to swing in a horizontal plane thereon, and is hinged at its rear end to the axle B, so as to swing thereon in a vertical plane.

For the purpose ot' adjustably supporting the draft-bar at a proper height, I secure rigidly to the under sides of the plow-beam and the coupling-beam a pair of bent plates, o and w, and through one o f these plates I pass a set screw, ai, the point of which rests against the other plate. By turning the set-screw in 01 out the outer ends of the coupling-bar and the draft-bar are raised or lowered.

I have shown and described one side or halt' of the cultivator, and the same description applies to the other half.

In operation: IVhen it is desired by the operator to turn the plows to the right or left of the direct line of draft of the implement, asin following a crooked corn-row or in passing an obstruction, this result is accomplished by` swinging the plow-handle to the right or left without lifting the plows, as heretofore. The plow-handle when swung tothe right, as indicated iu dotted lines in Fig. 3, operates through lever Oto turn the spindle H on pivots ff, thus bringing the wheelnto the position shown in dotted lines and causing the wheel and the plows to run inward toward the center of the draft-bar. Then the handle is returned to the position shown in full lines, the wheel is again turned parallel to the line of draft, and the plow-beam assumes a corresponding position.

I claim as my inventionl. In a cultivator7 the combination of the TOO swinging movement of the handle upon the l plow-beam, substantially as and for the purpose specified.

2. -In a cultivator, the combination of thel arched draft-bar, the plow-beam having acnl tivatorplow attached thereto, the forked axle rigidly secured `to the plow-beam, the coupling-beam hinged at its rear end to said axle, so as to swing in a vertical plane thereon, and

hinged at its forward end to the draft-bar to allow the latter to swing in a horizontal plane thereon, the Wheelspindle pivoted in the forked end of said axle, so as to swing in a 25 horizontal plane, the carrying-wheel mounted on the spindle, the arm rigidly secured to the -spindle and projecting backward therefrom,

the lever pivoted to the plow-beam and connected with said arm, and the plowhandle 3o secu red to said lever, all arranged to cooper-- ate substantially as and for the purpose specifled. Y

3. In a cultivator, the combination of the axle B, having the forked arm E, wheel-spin- 35 die H, having recess z', pivot-bolts ff, and wheel-hub j, having recess Z, all substantially as and for the purpose specified.
